To avoid the power unbalance of two inputs or input load-restriction,
ensure the two PV input cables are of the same type.
6.5.2 Assembling the PV Connector
SUNGROW provides corresponding plug connectors in the scope of delivery for
quick connection of PV inputs.
DC cables should be connected to the inverter via PV connectors which are
included in the scope of delivery.
To ensure IP65 protection, use only the supplied connector or the
connector with the same ingress of protection.
The PV cables must be multi-core cables.
The requirements of PV cables are as follows.

High voltage may be present in the inverter!
Ensure all cables are voltage-free before performing electrical
operations.
Do not connect the AC circuit breaker before finishing electrical
connection.
Use the MC4 DC terminal within the scope of delivery. Damage to the
device due to the use of incompatible terminal shall not be covered by
the warranty.
